Dear Amber users,
I have done 1ns simulation with explicit water model, and I want to get the average structure after equilibration from 50ps to 500ps using ptraj (amber8) using the input below.
After I load the average.pdb into leap to get the prmtop file, i got a lot of warnings like this:
WARNING: There is a bond of 0.049558 angstroms between:
------- .R<GLU 84>.A<CA 3> and .R<GLU 84>.A<CB 5>
WARNING: There is a bond of 0.230554 angstroms between:
------- .R<GLU 84>.A<CA 3> and .R<GLU 84>.A<C 14>
WARNING: There is a bond of 0.035128 angstroms between:
------- .R<GLU 84>.A<N 1> and .R<GLU 84>.A<H 2>
I copied several lines here, and the full leap.log is in the attachment. I also get some other snapshots from the mdcrd file, when i loaded these files into leap, no warnings was given.
---------------------------------
ptraj input:
trajin comp_wat_md.mdcrd 251 2500
center :1-277
image center familiar
strip :WAT
strip :Cl-
average average.pdb pdb
------------------------------------
Is it because of my ptraj script? Please give me some suggestions. Thank you very much.
